Both ends of the first spring 14 are in sliding contact with the flange 10 and the baffle 12 respectively. Under the elastic force of the first spring 14, the column 19 is in compression contact with the inner top surface of the hollow column 5.

[0041] Wherein, a depth scale line 4 for displaying the sedimentation depth is arranged on the periphery of the sedimentation tube 2 .

[0042] The mounting assembly includes a disk 6 arranged directly below the hollow column 5, a connecting rod 7 is fixedly connected between the top surface of the disk 6 and the bottom surface of the hollow column 5, and a plurality of circumferentially arrayed clamping seats 9 are fixedly mounted on the periphery of the disk 6, the number of the plurality of clamping seats 9 is equal to the number of the plurality of hollow columns 5, and the positions of the plurality of clamping seats 9 are aligned one by one with the positions of the plurality of hollow columns 5;

[0043] When the sampling assembly 1 is in a connected state with the mounting assembly, the peripheral clamping block 8 is inserted into the clamping seat 9 at the corresponding position in a damping sliding manner.

[0044] The switch assembly includes a limit plate 23 disposed near the middle and lower part of the sampling bottle 15, and a plurality of fixing rods 24 are fixedly connected between the periphery of the limit plate 23 and the inner wall of the sampling bottle 15;

[0052] Therefore, the utility model can complete the sampling operation at different depths in a single sampling process through the coordinated arrangement of the control component, the installation component and multiple groups of sampling components 1, thereby solving the problem in the prior art that multiple sampling operations are required to complete the overall sampling work, resulting in a cumbersome process of repeatedly taking and placing the device in the biogas tank, thereby increasing the difficulty of sampling.

[0053] Embodiment 2:

[0054] See also Figure 5 On the basis of the first embodiment, a docking groove 21 for cooperating with the column 19 is provided on the top surface of the connecting block 18 .

[0055] By setting the docking groove 21, the column 19 will be limited in the docking groove 21 when it is pressed and contacted with the connecting block 18, thereby improving the stability of the position state between the column 19 and the connecting block 18, avoiding sliding deviation between the column 19 and the connecting block 18 during the process of controlling the switch, thereby reducing the operating difficulty of the utility model.
